Pressure Switches

LF10 Pressure Switch

The LF10 pressure switches are used to regulate the tank pressure between two preset values on electrically driven air compressors. They are available with an unloader valve, which prevents compressors from starting under load, and an auto-off disconnect lever for manual cut off the compressor. A four port manifold style is available which provides a means for easy mounting of valves and gauges.

LF17 Pressure Switch

The rugged LF17 pressure switch is designed for the demanding requirements of larger, heavy duty commercial air compressors (up to 250psi). The sturdy painted steel case and cover resist the harsh conditions encounted in industrial applications. This style is available with an unloader valve to prevent the compressor from starting under load.

LF16 Water Pressure Switch

LF16 Water pressure switch provide time tested, reliable control for automatic water supply systems. The switch is universally acceptable for use as original equipment on water pumps or pumping systems.

LF37 Diaphragm Pressure Switch

LF37 diaphragm pressure switch is available for various sumps, effluent, and sewage application to control the liquid level. Various switch settings are available for to turn-on or turn-off the pump. The diaphragm pressure sensing design make it more reliable than traditional float ball mechanism.

LF10-W Water Pressure Switch

LF10-W pressure switch provide time tested, reliable control for automatic water systems. The switch is universally acceptable for use as original equipment on water pumps or pumping systems. Lf10-WR can prevent thepump from starting whenever the system falls considerable below cut-in pressure. Upon the restorations of the water supply, it will automatically cut-in. A manual reset level is depressed until a build up of system pressure permits automatic operation. Its simple design makes it easy to use for professionals and nonprofessionals alike.

LF31 Pressure Switch

LF31 pressure switch was designed for use in the HVAC industry where safety and reliability ar essential. Despite the design intent this series has proven to be a viable solution for many pneumatic applications as well. Available in vacuum, differential and pressure models with fine silver or gold cross bar contacts, the LF31 is capable of detecting pressures as low as .05 inches of water. Factory calibrated units maintain set point tolerances of +/-10% over a temperature range of -40 F to 185 F due to its molded silicone diaphragm and the stability of its glass filled polyester body. LEFOO offers multiple electrical terminations and mounting options as well as bleed holes and 3 different size orifices. This switch series is not only the leading product in the market offering the highest quality and reliability but is also the most economical.

LF32 Pressure Switch

LF32 switch is capable to sense tiny pressure change and widely used to control the flue of aerator, to monitor and fan and air conditioner; it is also for over heating protection and frost protection in industrial cooling system. Due to its outstanding design, the setpoint can been adjust visually.
